AWESOME!!! I have learned so much from your instructional videos over the past 6 months as a 35 yr old college student. They have helped me in maintaining a 4.0 GPA. Thank you so much! After watching some of your videos on topics I'm currently studying in precalc, I have come to a much fuller understanding of the concepts. I just made up a quadratic function, graphed it, and then produced a transformation for it and graphed it successfully. I've been watching your, and others', videos and studying, and practicing for the past six hours in preparation for my precalc exam tomorrow morning. I now feel more confident about it and am rather excited. Thanks again! You're awesome Mr. Tarrou!
YOU'RE WELCOME Brian, congrats on taking the plunge back into college...and thanks for studying so hard and making the effort to keep up that awesome GPA, I promise it will all pay off in the end:) I want to know if you felt the urge to shout BAM!!! after you completed that quadratic function?! lol Let us know how you did on that exam and please keep sharing this channel with your class and teachers too:D
After doing horribly in high school, the learning curve since I started college this past spring has been steep. I've had to take in A LOT of information. Surprisingly I have done well thus far. I had to start with College Algebra before I could take the required Trig class and I knew nothing about Algebra. I didn't even know PEMDAS. Like I said I did horribly from 6th grade on, because I didn't apply myself. Biggest regret of my life. Anyways, after I completed my quadratic function I shouted BAM!.... internally. It was a bit late so I couldn't wake my wife and kids. Lol! Unfortunately though, I got an 83 on my exam. I hold myself to high standards so it was rather disappointing. I need to excel if I am going to be an exceptional engineer. One thing I am good at though is persistence. I refuse to give up or settle for less than the best. Thanks again for your want to help people. The time that you, and the others that make these videos, put in to create these videos speaks volumes about your, and their, character. You are great people that care and take pride in teaching anyone who wishes to truly understand what they are learning.
We can tell that you have what it takes to succeed Brian! Motivation and the support of your wife and kids. Just keep this quote in mind..."A goal is a dream with a deadline" and "Believe and Achieve" Thanks again for the kind words, appreciation and sharing your story with us...we look forward to hearing that you have that diploma in your hand...BAM!!!
I am 53 this year and I am relearning maths as a hobby, as I love maths that much. Also, I am relearning maths for my other hobbies, namely programming, node compositing in 3D, etc.
Brian Coll, if you are going to be engineer, check out MajorPrep's channel. Also check out open source softwares that you can freely download from their official websites. They are *FREE* and it won't break your bank. You can use them for your studies. Lots of engineers use open source softwares in their homes after working hours. Some use it at work, if they so choose. If you want free alternative to AutoCad, consider FreeCAD. Another software is Onshape. You can get for free in student version and it is the nearest rival to SolidWorks. It is easy-to-learn. Both Onshape and SolidWorks have very similiar interfaces, as Onshape is developed by the very same programmers who had created SolidWorks. Onshape has forums where you can't resist viewing others' 3D works of engineering. One more software to check out is Blender and you can get that software at Blender.org and it is FREE. It does incredible 3D realism, physical simulations, animation, etc. In Blender, you can digitally test simulations of gravity, wind, liquid, etc against objects. It does more stuff than AutoCAD. Warning: Blender has a very steep learning curve, but you will love it, especially if you are artistic. For Blender tutorials, check out those by Neal Hirsig. Though his tutorials in backdated Blender may be few years old, they are still very useful. Neal Hirsig can pull you up very fast on Blender. Blender is a must-have for your portfolio as you can bring blueprints into 3D realism and turn them into animation, if you like. Companies will love that. Another free CAD software is DesignSpark Mechanical. DesignSpark website offer three free softwares that you can freely download. They do one for mechanical, another for electrical and last one for PCB. DesignSpark sells electrical components for PCBs. If you are into mechanics, you might want to see OpenFoam, a free software for CFD simulations. It digitally test wind, heat, gravity etc against objects. It shows movements of winds against vehicles. I haven't used that software. I am still learning Blender and I am 3/4 way there. Nowadays, you can get lots of free open source softwares not only for mechanical engineering, also for programming, electronics, animation, music, and all that jazz. For electronics, check out Fritzing, KiCad, Falstad Circuit, etc. I have app EveryCircuit (under $20). It does awesome circuit simulations and I have quickly learned electronics that way. When you download free open source softwares, visit Facebook groups for those, as you find lots of enthusiasts and professionals there. I go there a lot for brain-picking. If you are interested in free open source softwares like those for programming, check out my Google+ collections. Everyday, I go exploring softwares, free and affordables. I save their links. What you see in my collections, I use only 5% -10% of those softwares, as I am short on time. I am collecting them not only for myself, also for my nieces and nephews, and for few others of likewise interests.
Thanks for choosing, watching and learning from my channel Emmette Richardson I hope you will like, SUBSCRIBE, and tell others to watch and do the same to help these FREE educational channel groW and help others...BAM!!! Sounds like you could start with your class :)
I have a quiz on this today. And as a last minute attempt to save my grade, I decided to google transformations. I am SO glad I clicked on your video. You've got a new subscriber. Maybe I'll actually pass pre-calc this semester! Thank you!!!!!!
They CAN be a little trick but just keep telling your brain that you know the answers now and before you realize it ...you will! I'm glad I can be a part of you "transformation"... :D...that's the big smile you put on my face. Keep up the hard work, I promise it WILL pay off:)
Thanks for watching and subbing Omar Torres we all have our own teaching style and sometimes it just helps to hear a different one:) Please share my channel with your friends, class and teachers as an additional study reference and remind them it' important to like, SUBSCRIBE and keep sharing to help these free educational channels groW and remain FREE...BAM!!!
Just to make note, since leaving that first post, I been using your videos for all of my chapters. You are amongst the best instructors I have seen on RUclips. Much easier to relate to you due to your "stand in front of the chalkboard and give clear guidance" approach. Also, you're a pretty funny dude! Thanks for doing what you do!
I'm currently doing an AS level qualification in Maths in England. My teacher explained this horrifically (by comparison to you) and I just wanted to say thanks because it truly helped. Keep up the good work!
Best of luck on that exam mike greenfield I know you'll pass it like BAM!!! with all the studying you're doing to prepare! (we teachers appreciate that:)
THANKS for watching and learning from my channel oas1s2004 and for the insightful compliment:) Please help my channel continue to groW and help others by liking, SUBSCRIBING and sharing with others:D
All you have to do now @Taunee Skye is subscribe so you will always know where to find free math help for years with my 700+ videos...BAM!!! No more tears for your classmates either if you will please share this channel with all of them as well as your teacher! That will help us grow and keep helping others just like you:)
Sorry, not yet. I need to do another transformations video...or two. I am teaching calculus live for the first time this year and that is taking up almost all my efforts and time.
Thank you very much. This the only algebra video I have at the time for transformations of functions. I do a lot of work with transformations with trig functions, like my video Graphing Sine and Cosine without a Calculator. What you are describing is a vertical stretch.
Mr. Tarrou thank you very much for all your wonderful videos! I have high functioning autism with learning difficulties, and your methods of teaching math are unsurpassed. It's because of you that I held a 98 average in my college algebra class and 102 in trig. You really have a gift for teaching. I can't wait to watch your videos for my Calculus 1 class this summer! Keep doing what you do Mr. Tarrou your the best!! Ryan
You are very welcome Ryan Walker...and THANK YOU for taking the time to "Thank the Teacher", for choosing Tarrou's Chalk Talk to learn from, to share your experience and successes, and to send such a heartfelt comment! Students like you are why I continue to spend most of my free time growing this channel. My wife and I dream to see an "M" next to my subscriber count someday...so please spread the word and remind everyone to SUBSCRIBE & support FREE educational channels like mine! See you this summer:)
Umaasa ako na iyong natagpuan ang aking video helpful at gawin mo rin sa iyong mga pag-aaral ng matematika. Inaasahan ko rin nakuha ko ang pagsasaling ito tama :)
First comment on your channel... Just wanted to say thank you for taking your time to explain these concepts to all of us... we aren't all blessed with wonderful teachers such as yourself. Thank you for explaining every little step and keeping things as simple as possible... I'm in PreCalc now on my way(Hopefully) to Calc 3 and beyond and you have been my lifesaver! I've been watching your videos since Algebra, then Trig and now PreCalc and just wanted to take a moment to thank you and to let you know that you are making a huge difference! Thank you kind sir!
InvalidReject thanks for taking the time to share your appreciation and story with us and for using my videos to study with for so long! I hope you have been sharing my channel with others along the way and reminding them how important it is to to channel growth to like, subscribe, share thru social media and with all your friends and fellow students and teachers:D This also helps these educational channels remain free:) Sounds like you've just about reached the end of your math journey with my channel but we wish you all that you are deserving of in the future! And thanks for allowing #ProfRobBob to be a part of your study routine...BAM!!!
ProfRobBob Did you make a mistake at 7:35? I thought you were saying that you can't have a square root of a negative number, but at 7:35 you did a reflection across the Y axis by taking the square root of a negative number... Shouldn't it have been undefined?
***** While there is a negative x in the square root, you are not taking the square root of a negative number. You are substituting in negative x values (you can see this with the graph reflected over the y axis) then multiplying those x's by negative one and then subtracting two. That entire expression must be positive to be able to square root the value, you are not square rooting the x coordinate.
You should factor out the negative...it makes the transformations clearer as I added with an annotation in the video. I am making these videos as fast as I can...as I work full time as well. Thank you for the suggestion:)
You are one of the best teachers, the world has ever produced, I learned from you a lot. God bless you and give you strength to teach more, thanks......Anwar
Glad to hear my video helped you so much and thank you for liking and subscribing...that's how my channel grows:) I want to hear about that "A" you get on your test...so keep watching and sharing with others:D
Thank you! Always happy to hear that my teaching style has assisted in another break thru moment:)) Good for you to seek out extra help...glad you choose my channel to get it from!!!
Thanks for studying and subbing! Please share the love and this channel with your class and teachers too and help us keep growing and helping others...BAM!!!
BAM!!!...Congrats! Thanks for watching...I hope you will continue to share this free resource whenever you can even if your no longer in school and we wish you a lifetime of success wherever the road leads you!
Wow! Mr. Tarrou, you are a lifesaver! I have a pre-cal final next week and thanks to you, I'm gaining a much better understanding of the information on the exam. Thank you so much for doing this, keep them coming. I'm excited for Calculus next semester now that I've discovered your videos!
Happy to save you from that sea of math:) Thanks for choosing Tarrou's Chalk Talk to watch and learn from today and next semester. I hope you will tell all your friends and classmates where to find me and remind them to support & SUBSCRIBE to help my channel groW and help others like yourself achieve a better understanding of math:D
Oh man what your doing is amazing! Teachers like you give students like me who are decent but not the best another view point or a simpler way to look at things. I'm currently taking pre cal at a local community college. I feel like watching your videos before I go to lecture and after everything makes sense.
+Gilby reyes thats awesome...thanks for watching and subbing and taking the time to share your appreciation, experience and to "thank" the teacher! Motivated, prepared students like you are why teachers enjoy teaching:) Keep up those great study habits...it does make a difference! Please be sure to share my channel with all your friends, classmates and teachers as an additional study reference and remind them how important it is to like, subscribe, support the ads, share thru social medias and with others in order to help these free educational channels grow and remain free for everyone:D
I absolutely love seeing the enthusiasm in your lecture videos, Mr. Tarrou (I hope I spelt that correctly). it's just simply inspiring to see your passion like this! please continue making more videos!
You did…and THANK YOU:) As long as I have motivated students like you watching and supporting! As long as my channel keeps growing…I plan on making more videos. Growing an educational channel is much harder than the humor, gaming, music, etc. channels…but we won't give up our dream to see a "M" next to my subscriber count someday:) You can help that growth by spreading the word about my channel and reminding them to support and SUBSCRIBE!
Thanks for clarifying...never heard that description before...sounds like you're on the right road! Thanks for watching and commenting and please share my channel with others who may find it beneficial, I grow through the help of my viewers:D
THANK YOU and Thanks for your feedback...I did the layers on the graph that way to show the movement and did note in the video that it might be a bit confusing. Are you a teacher as well?
A Supplemental Instruction class is a student teacher. A student who already passed the class with a high grade qualify for this. We also have a Supplemental Instructor who helps us for our Chemistry class. In short words it's a tutor. And your video was awesome thnx a million... You seem like a very fun teacher to have. Lucky students.
+ross williams you're welcome and THANK YOU for taking the time to seek outside help to study with and for choosing my channel to like, sub and learn from! Please tell all your classmates to watch and do the same:D (maybe even share with your professor as an additional study reference to add to their syllabus:)
These videos are awesome man! No joke. Its so nice that you breakdown how and why these rules and equation work when they're applied. I have read and reread my book several times and after watching this video it all makes sense now. haha. Thanks for the help.
Sounds like a perfect time for a ...BAM!!!...lol You're welcome and thanks for studying and subbing to this channel, please tell all your friends, classmates and your teacher to watch and do the same to help us keep growing and helping students learn for free:)
Thank You so much!!! You just clarified everything for me! I have my first pre-cal test tomorrow!! After watching this video I can actually practice some problems before my test!
You're welcome and thanks for watching them!...Canada's a bit far but now that you've subscribed you can be in my class anytime you feel the need to learn something new...lol It's not quite the same, but if you got a group of students together from your class and all watched my videos together it could be the next best thing!!!...you should give it a try:)
I really appreciate your videos. I made the mistake of taking a precalculus class for the summer term. My professor has to move pretty fast due to the terms being compressed into six weeks so I'm finding these really helpful. Thanks!
Liquid Bastard I'm glad to hear they are helping... and you can help us keep growing by liking, subscribing, supporting the ads and sharing with your friends, classmates and teachers as an additional study reference as you remind them to lie, sub and keep sharing...BAM!!!
Love your excitement. I just started teaching basic computer networking and like math the material can get dry. I'll have to try out some of your techniques!
thank you so much! i have been slightly confused in my algebra class. everything you said was clearly spoken and understandable! You're work is appreciated.
You are very welcome...glad I could help! Thanks for watching and taking the time to share your appreciation. If you continue to find us helpful please take the time to like, subscribe, share this channel thru social medias, with classmates and especially your teacher to help us keep growing and helping others...BAM!!!
The - in front of the x reflects the graph over the y axis:) You may want to rewrite the equation as sqrt(-(x+2)) to more clearly see the reflection over the y axis and then the shift left two.
You're welcome...sounds like the perfect time to sub and share this channel with your class and teacher as an after school study reference so ALL the students looking for help like you did, will know where to find us...BAM!!!
...and THANK YOU jason HAN for learning, liking and subbing! Please continue to help me groW by sharing with everyone, remind them to Like, Subscribe, Support, Share, Support the ads, spread the word thru social media, etc. These are the things that keep free educational channels like mine FREE...BAM!!!
THANK YOU SO MUCH ProfRobBob you are byfar 10x better than EVERY math teacher i've had so far. your videos always give me big help and understanding whenever i need help studying for a test. keep making videos and being such a great help to everyone watching your videos!!!
You are so welcome instantlight301 and THANK YOU for taking the time to study and choosing #ProfRobBob to learn from, like, sub and share such a complimentary comment with! Students like you are why I teach and continue to make these videos and work so hard to groW this channel! Please keep sharing your experience and my channel with everyone:D Our goal this year is to finally reach 100,000 subscribers...BAM!!!
You have to work from within the parentheses out right!? So with your first equation f(1)=1^2 is 1 of course. Your second equation would have to have an x value of 3 to yield the same answer as 1 because you subtract 2 before applying the power of two. f(3)=(3-2)^2 equals (1)^2 or one. I hope this help you see the horizontal shift to the right that gives the same y values. Thank you very much for subscribing. My wife and I appreciate your support.
You're welcome again inthelight1776 ! I'm glad to see that my lessons are still helping you. But remember, it's not just because of me...if it weren't for YOU taking the time to study there might not be success...it's all about teamwork, even when it's a team of two:)
Thank YOU for NOT giving up and seeking outside help! Don't hesitate to ask your teacher or another teacher for live help if you need it...that's what we are here for and why we teach:) Practice, study, learn, repeat!
I really wish I could have you as my professor! You're amazing! I love your handwriting and your way of explaining things, makes everything seem so simple and easy when it has really not been!
Thanks for the compliments! Sounds like the perfect time to share this free resource with your class and teacher so everyone will know where to find after school help for free...BAM!!! ...and please remind everyone to sub and keep sharing! (I also hav a few cursive videos if you need a break from math:)
You can try Graphing Parabolas in Standard Form. You can see many of the transformations in that video...but it is not specifically made to point out the transformations like this video.
Thank you for all your kind words...I learned calligraphy in middle school and it stuck! Keep watching and learning and if you like my channel...share with your friends:)
In your example, is it sqrt(-x) -2 or sqrt(-x-2) If sqrt(-x-2), you may find it easier to understand by factoring out the - to get sqrt(-(x+2)) so you can more easily see the reflection over the y axis and the shift to the left 2 places. Thank you for watching and the nice comment.
Sir I am from India..... really thanks for your video...i teach physics....and love to listen math lecture from you...plz keep doingit... it....spread happiness and knowledge....
Thanks for listening to my lessons...I'm sure you know far more math than I do as a physics teacher but I really appreciate when other teachers enjoy my channel. I hope you are sharing it with your beginner students too:) I appreciate any and all support here in Florida abhijeet shukla :) You too, keep teaching our future!
Just wanted to say thank you for making this video! It really helped! I was trying to look for a video like this on Khan Academy but I couldn't find one and I'm so happy I came across your account!
You're welcome Sasha Podzorov ! ...and THANK YOU for not giving up until you came across Tarrou's Chalk Talk:) I hope you will return and Like, Share and SUBSCRIBE to my channel and spread the word to others who could benefit as well:D
:D I really like where I teach even though it almost burned down this week. But, if you ever need extra help, I hope to have a video ready for you. They are all full lessons and not just examples without explanation. I have over 300 at the moment. I hope you do great in your class this year!!!
Thank you Prof you have just helped make my online algebra class a lot easier to understand, even though I will be taking the course over in a classroom setting, I will be better prepared for this class, since I haven't taken algebra in over 30 years
You're welcome Lori. Are you going back to school to fulfill a dream or making a career change?!...either way I wish you much success and it looks as if you are off to a great start in preparedness!
You're welcome and thanks for watching and learning. I'm teaching IB for the first time this year after 22 years of traditional and AP classes and I LOVE it!!! Please like, sub and share this free resource with your teacher too:D

I've been watching your videos since Algebra, then Trig and now PreCalc and just wanted to take a moment to thank you and to let you know that you are making a huge difference! Thank you kind sir!
InvalidReject thanks for taking the time to share your appreciation and story with us and for using my videos to study with for so long! I hope you have been sharing my channel with others along the way and reminding them how important it is to to channel growth to like, subscribe, share thru social media and with all your friends and fellow students and teachers:D This also helps these educational channels remain free:)
Sounds like you've just about reached the end of your math journey with my channel but we wish you all that you are deserving of in the future!
And thanks for allowing #ProfRobBob to be a part of your study routine...BAM!!!
ProfRobBob Did you make a mistake at 7:35? I thought you were saying that you can't have a square root of a negative number, but at 7:35 you did a reflection across the Y axis by taking the square root of a negative number... Shouldn't it have been undefined?
***** While there is a negative x in the square root, you are not taking the square root of a negative number. You are substituting in negative x values (you can see this with the graph reflected over the y axis) then multiplying those x's by negative one and then subtracting two. That entire expression must be positive to be able to square root the value, you are not square rooting the x coordinate.
ProfRobBob
omg... thanks
***** you're welcome, thanks for watching and subbing too!
Sir, you make this world a whole lot better. Thank you!
You should factor out the negative...it makes the transformations clearer as I added with an annotation in the video. I am making these videos as fast as I can...as I work full time as well. Thank you for the suggestion:)
You are one of the best teachers, the world has ever produced, I learned from you a lot. God bless you and give you strength to teach more, thanks......Anwar
Glad to hear my video helped you so much and thank you for liking and subscribing...that's how my channel grows:) I want to hear about that "A" you get on your test...so keep watching and sharing with others:D
Thank you! Always happy to hear that my teaching style has assisted in another break thru moment:)) Good for you to seek out extra help...glad you choose my channel to get it from!!!
i love you Mr. "Turoo" your videos are so helpful and the way you teach and speak make it easier to understand.
Thanks for studying and subbing!
Please share the love and this channel with your class and teachers too and help us keep growing and helping others...BAM!!!

@@stephenamerak994 THANKS!!!
Wow! Mr. Tarrou, you are a lifesaver! I have a pre-cal final next week and thanks to you, I'm gaining a much better understanding of the information on the exam. Thank you so much for doing this, keep them coming. I'm excited for Calculus next semester now that I've discovered your videos!
Happy to save you from that sea of math:) Thanks for choosing Tarrou's Chalk Talk to watch and learn from today and next semester. I hope you will tell all your friends and classmates where to find me and remind them to support & SUBSCRIBE to help my channel groW and help others like yourself achieve a better understanding of math:D
Oh man what your doing is amazing! Teachers like you give students like me who are decent but not the best another view point or a simpler way to look at things. I'm currently taking pre cal at a local community college. I feel like watching your videos before I go to lecture and after everything makes sense.
+Gilby reyes thats awesome...thanks for watching and subbing and taking the time to share your appreciation, experience and to "thank" the teacher!
Motivated, prepared students like you are why teachers enjoy teaching:) Keep up those great study habits...it does make a difference!
Please be sure to share my channel with all your friends, classmates and teachers as an additional study reference and remind them how important it is to like, subscribe, support the ads, share thru social medias and with others in order to help these free educational channels grow and remain free for everyone:D
You're welcome...and THANK YOU for watching and subscribing!
I absolutely love seeing the enthusiasm in your lecture videos, Mr. Tarrou (I hope I spelt that correctly). it's just simply inspiring to see your passion like this! please continue making more videos!
You did…and THANK YOU:) As long as I have motivated students like you watching and supporting! As long as my channel keeps growing…I plan on making more videos. Growing an educational channel is much harder than the humor, gaming, music, etc. channels…but we won't give up our dream to see a "M" next to my subscriber count someday:) You can help that growth by spreading the word about my channel and reminding them to support and SUBSCRIBE!
Thanks for clarifying...never heard that description before...sounds like you're on the right road! Thanks for watching and commenting and please share my channel with others who may find it beneficial, I grow through the help of my viewers:D
The way you teach makes me understand the principles of transformations
What a kind thing to say Anwar:)
…and THANK YOU for choosing my channel to watch and learn from with all the choices there are availably!
THANK YOU and Thanks for your feedback...I did the layers on the graph that way to show the movement and did note in the video that it might be a bit confusing. Are you a teacher as well?
You are very welcome:) Thank you so much for watching and the nice comments!
A Supplemental Instruction class is a student teacher. A student who already passed the class with a high grade qualify for this. We also have a Supplemental Instructor who helps us for our Chemistry class. In short words it's a tutor. And your video was awesome thnx a million... You seem like a very fun teacher to have. Lucky students.
@thescrona Your are welcome. Glad I could help
This the best video I have seen, you explained it fore the normal person to understand. Thank you!!!
Thanks for studying with my channel...please sub and share if you continue to find it helpful!
You are one of the best teachers online! Pls keep up the great work!
THANKS for the compliment and for watching!
Please sub and share this free resource with all your friends, classmates and teachers too:D
AWWW... Thank you very much\:D/ I appreciate you watching and leaving such nice comments!
Man you are single handedly getting me through precalculus in college. Thank you for your thorough explanations in plain english
+ross williams you're welcome and THANK YOU for taking the time to seek outside help to study with and for choosing my channel to like, sub and learn from! Please tell all your classmates to watch and do the same:D
(maybe even share with your professor as an additional study reference to add to their syllabus:)
Thank you so much! I have a test on this tomorrow, and I feel so much more confident after watching this video!
You are very welcome. Thanks for watching:)
You explained it so well. Thank you!!
You're welcome...thanks for studying...please sub and share too!
Thank you so much for all of your videos - nothing my precalc teacher said made sense until I watched these!
These videos are awesome man! No joke. Its so nice that you breakdown how and why these rules and equation work when they're applied. I have read and reread my book several times and after watching this video it all makes sense now. haha.
Thanks for the help.
Sounds like a perfect time for a ...BAM!!!...lol
You're welcome and thanks for studying and subbing to this channel, please tell all your friends, classmates and your teacher to watch and do the same to help us keep growing and helping students learn for free:)
Thank You so much!!! You just clarified everything for me! I have my first pre-cal test tomorrow!! After watching this video I can actually practice some problems before my test!
You're welcome and thanks for watching them!...Canada's a bit far but now that you've subscribed you can be in my class anytime you feel the need to learn something new...lol It's not quite the same, but if you got a group of students together from your class and all watched my videos together it could be the next best thing!!!...you should give it a try:)
I really appreciate your videos. I made the mistake of taking a precalculus class for the summer term. My professor has to move pretty fast due to the terms being compressed into six weeks so I'm finding these really helpful. Thanks!
Liquid Bastard I'm glad to hear they are helping... and you can help us keep growing by liking, subscribing, supporting the ads and sharing with your friends, classmates and teachers as an additional study reference as you remind them to lie, sub and keep sharing...BAM!!!
Love your excitement. I just started teaching basic computer networking and like math the material can get dry. I'll have to try out some of your techniques!
Jack Berning warning...don't jump in with a BAM!!! on a slick floor:) lolThanks for the compliment and I hope you enjoy teaching as much as I do!
thanks very much Prof, transformations tricked me a lot
You're welcome ...thanks for watching!
Thank you sooooooo much!
We got notes over this last week in class, but I didn't understand it at all, and this clarified it.
thank you so much! i have been slightly confused in my algebra class. everything you said was clearly spoken and understandable! You're work is appreciated.
You are very welcome...glad I could help!
Thanks for watching and taking the time to share your appreciation. If you continue to find us helpful please take the time to like, subscribe, share this channel thru social medias, with classmates and especially your teacher to help us keep growing and helping others...BAM!!!
Thank you so much:) I have 322 more videos to choose from!!! I am glad I could help.
The - in front of the x reflects the graph over the y axis:) You may want to rewrite the equation as sqrt(-(x+2)) to more clearly see the reflection over the y axis and then the shift left two.
Thank you for helping me understand this a little better than I have understood the past week I've done in class.
You're welcome...sounds like the perfect time to sub and share this channel with your class and teacher as an after school study reference so ALL the students looking for help like you did, will know where to find us...BAM!!!
Thank you sir. for some great explanations. I am very thankful that i found you on RUclips.
You're welcome and thanks for watching...please sub and share this free channel with everyone!

Thank you! I have a test in precalculus on this subject and never really understood the concepts of transformations, but now I do:)
THANK YOU SO MUCH ProfRobBob you are byfar 10x better than EVERY math teacher i've had so far. your videos always give me big help and understanding whenever i need help studying for a test. keep making videos and being such a great help to everyone watching your videos!!!
You are so welcome instantlight301 and THANK YOU for taking the time to study and choosing #ProfRobBob to learn from, like, sub and share such a complimentary comment with! Students like you are why I teach and continue to make these videos and work so hard to groW this channel! Please keep sharing your experience and my channel with everyone:D Our goal this year is to finally reach 100,000 subscribers...BAM!!!
18 years of teaching...
Thanks for choosing my channel to watch and learn from...I hope you'll be back and bring all your friends!!!
You have to work from within the parentheses out right!? So with your first equation f(1)=1^2 is 1 of course. Your second equation would have to have an x value of 3 to yield the same answer as 1 because you subtract 2 before applying the power of two. f(3)=(3-2)^2 equals (1)^2 or one. I hope this help you see the horizontal shift to the right that gives the same y values. Thank you very much for subscribing. My wife and I appreciate your support.
Right on! you're doing a great service for struggling students!!
Amazing lectures, thank you very much for your help!
Thanks for watching...please sub and share this free resource with everyone, especially your teacher...BAM!!!
thanks, this is awesome! I didn't understand what my teach was trying to explain at all. this clears up a lot.
Thanks again. I wouldn't succeed in math without your videos!
You're welcome again inthelight1776 !
I'm glad to see that my lessons are still helping you. But remember, it's not just because of me...if it weren't for YOU taking the time to study there might not be success...it's all about teamwork, even when it's a team of two:)
I have a video introducing the concept of even and odd functions, which sounds like what you want.
I love your teaching!!! I understand the concept much better! Thanks
you seriously helped me out a lot on my Calculus Homework!!!!!!!!!
You are the greatest to ever do this !!!!!!
THANKS for watching...please sub and share too:D
this was very confusing the way my professor taught us but you explained it clearer, thank you!
+Zahraa Abdulhadi you're welcome and thanks for taking the time to find outside help and subscribe!
Thank you so much i am currently failing 9th grad algebra 1 and this will help me so much !!!!!!!!!!!!!!!!!!
Thank YOU for NOT giving up and seeking outside help!
Don't hesitate to ask your teacher or another teacher for live help if you need it...that's what we are here for and why we teach:)
Practice, study, learn, repeat!
I really wish I could have you as my professor! You're amazing! I love your handwriting and your way of explaining things, makes everything seem so simple and easy when it has really not been!
Thanks for the compliments!
Sounds like the perfect time to share this free resource with your class and teacher so everyone will know where to find after school help for free...BAM!!! ...and please remind everyone to sub and keep sharing!
(I also hav a few cursive videos if you need a break from math:)
this is so helpful for me teaching my students in my supplemental instruction class, thank you!
You can try Graphing Parabolas in Standard Form. You can see many of the transformations in that video...but it is not specifically made to point out the transformations like this video.
THANKS! This was one of my early videos filmed with a different camera and location. My newer videos are done with all that in mind:)
Thank you for all your kind words...I learned calligraphy in middle school and it stuck!
Keep watching and learning and if you like my channel...share with your friends:)
In your example, is it sqrt(-x) -2 or sqrt(-x-2) If sqrt(-x-2), you may find it easier to understand by factoring out the - to get sqrt(-(x+2)) so you can more easily see the reflection over the y axis and the shift to the left 2 places. Thank you for watching and the nice comment.
Thanks, these videos have helped me have a clearer understanding of these concepts!
Start summer semester in Calculus 1 on monday! Getting my review in now on the pre calculus to fresh up my memory and i have rob bob to help me again!
Great to see you back...and I see those great study habits still prevail...BAM!!!
Great teaching and explanations Rob; I wish there were more math teachers like you.
